Application filed April Z0, 1900. Serial No. 13,586. (No model.) i 1 l?) nl] [Itho/11, it mfr/1,1 concern,.-

lle'it known that I, EDWARD H. ELDER, a States of America, and a resident of Chicopee, in the county ot' Hampden and State ot' l\Iassacl1iisetts,have invented certain new and usefulIinprovementsin Ejec tor Mechanism for Guns, of which the follow- `ing` is a full, clear, and exact description.

This invention relates to improvements in ejector mechanism for firearms, cially Shotguns, either double or reled.

The object ofthe invention is to produce an ejector or extractor device for the shells which is automatically operated on the breaking down ofthe gun, which is simple and efficient and not liable to derangement or to become displaced or lost; and the invention consists in the construction and combination or arrangement of parts,all substantially as will be hereinafter described, and set forth in the claims.

Reference is to be had to the accompanying drawings, in which the present improved ejector mechanism is illustrated, and in which- Figure l is a central longitudinal section through the portion of a shotgun in which the ejector is contained, showing the parte which constitute the latteras in their relative positions when the gun is closed. Fig. 2 is a substantially similar longitudinal sectional View, but showing the gun as broken down and the parts of the ejector as in their changed positions as insured by the breaking down or opening of the gun. Figs. 3, at, and`5 are perspectiveviews in detail ot the parts which constitute the ejector device.

Simi larcharacters of reference indicate corresponding parts in all of theviews.

In the drawings, A represents the frame of the gun, comprising the forward extension a, to which the bottom lug h ofthe barrel or barmore espesingle barrels B is hinged at d, the frame having the' upwardly and forwardly inclined portion f in advance of the hinge to act as a cani-surface in relation to the catch-releasing rod g, hereinafterdescribed.

The bottom lug D under the barrel is pro- Avided with the longitudinal bore or socket /t,

in which is longitudinally movable the stem '1f of the extractor or ejector, the flange or rearend enlargement 'z2 being when the gun is closed disposed within the rabbeted seat h2 therefor, said seat merging into or opening to the shell-receiving chamber of the barrel, as usual. r

` The front end portion of the ejector-stem is formed with a central longitudinal passage is,

preferably by making t-his portion of the stem I position and for retaining it in such .closed position `until the'A catch is displaced transversely relativeto the length of the ejector to release the latter. The said catch is shown as in the form of a cylindrical block set for an axial play within a socket 14 therefor Vertically through the bottom lug b and inwardly merging into or connecting with the longitudinal bore h of the lug. The upper engaging end of the catch, as plainly shown in Fig. 5, is constructed with the forwardly-facing catch members l5 15, rearwardly beveled, as seen at 1U, and having between them the further endwise-extended portion, which is beveled, as seen at 17, from its rear edge downwardly and forwardly,constituting an incline suitable for receiving the impingement there against of the cani or wedge-shaped end 18 of the ejector-catch-releasing rod g. The cylindrical block having the engagement and inclined portion at its inner end, as described',

has an elevatingforce imparted thereto byv the spring which bears against its lower end and which is conti ned under compression between such lower end of the catchand the screw-plug ym., which screw engages into and closes the lowerend of the aforesaid socket 14.

The catch-releasing rod for' convenience and practicability formed in two sections 2; and 23, as shown in Fig. 4, the forward end' of the section 23' being provided with the shoulder-flange 25,axially screw-threaded and IfOO tapped tofreceive the rear screw-'threaded end portion of the stem-section 22therein-', so

that when theA parts are assembled theV two v -portions are as one piece.

The rear portion of the catch-operating stem having the'wedge- 'shaped extremity enters the central passage t3 in the stem or shank of the ejector, the Ver-` tically-widened portion 21 of said Awedge-y formed extremity or cam depending so as to have .its positionl between the opposite marp gins of the longitudinal slot or recess t,

catchtorelease the ejector from the engagewherebythe said part g will be restrained from any undue rotational movement-,and the engagement of the portion 17 inan'd through 'v the said recessed'portion 114 of the ejector-stem not only insures that the ejector-stem will not be turned, butalso serves yto prevent the catchyl from becoming turned, whereby such incline 17 would be displaced from its proper relative position for receiving theimpingement of the cam 18 thereagainst when the barrel issw ung open, The spiral spr-ing 'n is pro- -vide'd between the shoulder`25 ot the catch- 'releasing rod andthe forward e'nd of the ejector-stem.

The action of closing'the gun insures that the ejector will be moved longitudinally forward and closed as. ordinary, at which time the catch 15 engages the catch-notches 10 10, provided at the bottom ofthe stem of the ejector, as shown in Figui.V Now'when the gun is broken down the forward portion f of the frame, which has its surface more or less sharply angular to the length of the party,

constitutes an abutment whereby the swinging of the barrel and bottom lug insure, as the catch-releasing rod is' swung therewith into the rearwardly and upwardly inclined position shown in Fig. 2, a rearwardly longitudinal forcing of the said ro'd g withinthe bore h in the bottom lug, and the cam 18 in working against the incline 1,7 of the catch j crowds such catch endwise, so that the catch mem'- ybers 15 become disengaged from the notches 10 ofthe ejector, leaving the latter freed to the reaction of the spring fn, which projects the ejector rearwardly.

While. the wedge or cam of the catch-ie.`

leasing' rod g inits endwise thrust insures the necessary transverse displacement of the ment had by itsV .catch portionA 10 10, such transverse displacement effected by the said cam 18 is not `so great as to place the catch portions 15 15'below the path of the deeper vertical catch portions 13 of the notch 12,

butiwill intercept such portions if the out-' throwing force of the spring n is sufficient to project the extractor so far as to bring the notches l2 into proximity to the catch j, and' thus there is no liability atany time of the ejector being thrown' entirely out from the bore or socket in which it hasv its requisite eX- t-ent of back-and-forth play.

The face f of asuitablyrecessed forward upper part of the frame of the gun efficiently serves as the abutment or resistant against -whihth 'swinging or the 'ban-situa inging lcause the forward end `'of the catch-releasing. 'i

rod to be brought; but any suitabletixed part ofthe frame, having its surface suitably angular or eccentric to the pivotal point d, will suie to insure the same result. The rear wedge-shapedjend'of the ycatch-releasing rod g, after the rod has been so 'far vmoved as tov force the catchfrom its engagement with the ejector, will have come adjacenty thesolid rear part ofthe ejector, so that the last portionv .of the thrust impartedto the'Tr'od` g will cause such'rod to positively and forcibly drive the ejector. rearwardlyshould the spring fail todo thew'ork by Areason ofacartridge-shell sticking in the chamber, and in order to provide that the capability of this action in such' contingency shall exist the 'normal location of therear end of the rod relating tothe inner end wall 5 within the socket of the tubular ejector-stem isat less distance from thev said down gun, in combination, -the barrel or barreis having, in an under portion or bottom lug thereof, the longitudinally-movable ejector,

the stem of which is tubular and constructed.
